Uhm, Jeri, one quibble. I thought I'd make 51 into 61 at least, since otherwise

1990
- 51
______
1939 DOB
and if she gets married at 16, that makes it
+16
------
1955
and that will give her a daughter leaving home for the wilds of SF in 1960 at the age of 5.
Sixty-one works about right, tho maybe not for doing the continent with a 33yr old student. At least she dies happy, right?
Blessings,
Barbara
